7.5 Consider the amplifier of Fig. 7.4(a) for the case VDD = 5 V, RD = 24 k, kn(W/L) = 1 mA/V2, and Vt = 1 V. (a) Find the coordinates of the two end points of the saturation-region segment of the amplifier transfer characteristic, that is, points A and B on the sketch of Fig. 7.4(b). (b) If the amplifier is biased to operate with an overdrive voltage VOV of 0.5 V, find the coordinates of the bias point Q on the transfer characteristic. Also, find the value of ID and of the incremental gain Av at the bias point. (c) For the situation in (b), and disregarding the distortion caused by the MOSFET’s square-law characteristic, what is the largest amplitude of a sine-wave voltage signal that can be applied at the input while the transistor remains in saturation? What is the amplitude of the output voltage signal that results? What gain value does the combination of these amplitudes imply? By what percentage is this gain value different from the incremental gain value calculated above? Why is there a difference?
